Morphological and Ecological Traits Explain Variation in Desiccation Tolerance Among Bees
We assessed the desiccation tolerance in 22 bee species from the Greek island of Lesbos. Larger bees lost water more slowly and survived longer, while survival declined with increasing water loss rate and water content at mortality. Morphological and ecological traits shaped physiological responses, highlighting trait‐based mechanisms underlying ...

Phylogeny of Halictidae with an emphasis on endemic African Halictinae [PDF]
We review the literature on phylogeny, fossil record, biogeography, and social evolution in Halictidae. We then present a phylogenetic analysis of tribal, generic, and subgeneric relationships within the subfamily Halictinae using a combined data set of three nuclear genes: long-wavelength (LW) opsin, wingless, and EF-1α.

Heteranthery in Commelina communis integrates a temporally structured two‐step selfing system: prior selfing via bud pollination followed by delayed selfing mediated by the medium‐length stamen (M‐anther). By functioning both as a pollinator reward and a mediator of delayed selfing, the M‐anther links outcrossing with reproductive assurance within a ...

ABSTRACT The breeding systems of Lutruwita/Tasmania's threatened Epacris taxa are poorly known. Our main objective was to determine the pollinators of several endemic species and explore for relationships between pollinators, floral morphology, flowering time and habitat. The Epacris have limited variation in floral traits and exhibit generalist floral

Change in habitat over time for the rare, endemic Pediocactus paradinei
Pediocactus paradinei is a rare endemic cactus on the Colorado Plateau that may be increasingly vulnerable to ongoing ecological and climatic change. In 2022, we resampled ecological monitoring plots originally surveyed in 2005 to assess changes in vegetation, habitat conditions, and characteristics related to pollinator habitat across the species ...

Structural Colour in Bees (Hymenoptera: Anthophila) Is Linked to Climate and Latitude
ABSTRACT Aim Environmental drivers frequently predict global patterns of colour diversity, but whether such patterns depend on the underlying colour mechanisms—pigments or microscopic structures—has scarcely been considered. Structural colour may have different functional properties that result in different associations with environmental variables ...

Diversity of bees (Hymenoptera, Apiformes) in extensive orchards in the highlands of Jordan
Bees visiting the blossoms of fruit trees were surveyed for the first time in Jordan. A transect was determined in Ebbin village in Ajlun (32° 22″ N, 35° 49″ E) where the bees were collected from blossoms of stone fruit trees.
